Abstract
Systems and methods for carrying out seismic surveys and/or conducting permanent reservoir monitoring with autonomous or remote-controlled water vehicles, including surface and submersible vehicles, are described. Additional methods carried out by autonomous or remote-controlled water vehicles and associated with seismic surveys further described.
Claims21
A method of seismic surveying, comprising:
- deploying a plurality of water vehicles in a region for surveying, the water vehicles comprising one or more autonomous or remotely controlled surface and/or underwater vehicles, at least one of such vehicles having motion dependent primarily on harvesting wave energy;
- and
- coupling at least one hydrodynamic body to one or more of the water vehicles, the hydrodynamic body having a sensor for recording seismic data.
A method of seismic surveying, comprising:
- towing one or more seismic streamers with a tow vessel, the one or more seismic streamers having seismic sensors coupled thereto for recording seismic data;
- deploying one or more water vehicles in an area generally proximate to the seismic streamers, the water vehicles comprising one or more autonomous or remotely controlled surface and/or underwater vehicles, at least one of such vehicles having motion dependent primarily on harvesting wave energy;
- and
- using the water vehicles to support the seismic survey.

A method of seismic surveying, comprising:
- deploying one or more water vehicles in a seismic survey area, the water vehicles comprising one or more autonomous or remotely controlled surface and/or underwater vehicles, wherein the water vehicles have one or more seismic sensors coupled thereto, at least one of such vehicles having motion dependent primarily on harvesting wave energy;
- deploying one or more source vessels in the seismic survey area, the source vessel having one or more sources coupled thereto;
- advancing the water vehicles along a predetermined path;
- advancing the source vessel along a predetermined path;
- emitting acoustic signals from the one or more sources to generate seismic data;
- and
- recording the seismic data via the seismic sensors coupled to the water vehicles.
